I would, if it would happen, but I don't think it will either. I don't think the 6L80 will handle the RPMs or the power either and can't see a 6L90 cutting it either because of the RPMs. I'll have to see if I can find some documentation.

Cool idea, but I just don't see it happening, mostly because 'Father already said so :(

Y'know, and I'm just being dorky, but the COPO cars were ordered under the same umbrella as fleet and police vehicles. Aren't they not eligible for CAFE standards? GM could (technically) sell an LS7 with a Turbo 400 and not worry about CAFE.....

Check teh threads here the LS3 and L99 are essentially the same motor, with the LS3 losing a feature (cyl deactivation). That said keep dreaming, the days of low production factory freaks are long gone....

COPO stuff was installed at the dealer. I can see a dealer doing an LS7 like Harwell, Berger, etc... expect it to cost $50k+ from a dealer though :(

Perhaps he meant the first Yenkos and such that had the 396s pulled at the dealer and stabbed the L72s in there Actual COPOs were factory cars to my understanding though

Would an LS7 really need a 400? I'm not arguing, I'm only asking. Maybe because either six-speed autos (6L80 and 90) won't rev' up to the LS7 redline?

I dunno. I don't think 20 hp would be worth any extra costs involved to produce the car as a whole. Nor would I feel like giving up the AFM just to say "LS3", imo.

Is someone really going to feel that 20 horse'?... I think that six-speed auto' is going to make-up for a lot of the gear spread problems (well, that's what I think) that the 4L60/5/70 had. I mean, shifting at 6200 in my car would bring RPMs all the way down to about 3800 in the next gear. Talk about out of my powerband! I don't think these six-speed autos' are going to be lagging to the sticks in any way But I digress...

You can make your own 427 with the 6.2 anyways with a little bore and some stroke

Stock, no. Modded? Absolutely. Especially if you're drag racing the car When you start making the kind of power a TT LS7 can make, OD trannys usually don't hold up nearly as well. If I were building a drag car, I'd gut that bad boy out, throw an F1 on there, and drop in a Turbo 400. No need for the extra gears and I'd rather have the stronger 3-spd.

I still want my high rev+handling package Z/28 though. But that's just me.

There's no way that someone dropping the LS7 in their Camaro is leaving it stock. You would have come too far to just leave it stock. At that point, it's time to go for the gold.

The 6Lxx series of auto trannies are all very similar in design. The difference lies in their power-handling abilities. I don't know the exact relationship, but I know for sure: the higher the last two numbers (50, 80, 90, etc) the tougher they're built (materials, gear thickness in some cases) in order to handle higher torque capacity of the engine they're mated to. The 6L50 can rev to 7000 (see: Cadillac V6 DI), so I have no doubts the 6L80 can, too. After all; it's already revving to ~6600 in the LS3 Vette.
